Common problems

Problem Solution
The button is still gray after uploading? At least 2 valid .docx files are required for merging.
The format is messed up after merging? It is recommended to use the standard .docx generated by Office 2007 or later, and avoid enabling protected view.
The file is too large to upload? The single file size limit is 50 MB, you can try splitting the document before merging.
